M ECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 720,140, dated February 10, 1903.

ApplicationV filed August 5, 1902.

To L ZZ whom, it may concern:

Be it known that I, JOSEPH E. HAUsFELD, of Cincinnati, in the county lof Hamilton and State of Ohio, have invented certain new and useful Improvements in Mechanical Movements; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use thesame.

My invention relates to an improved mechanical movement, and more particularly to improved mechanism for alternately rotating a driven shaft in opposite directions by means of a driving-shaft continuously revolved in one direction, the object of theinvention being to provide improved means specially adapted for operating the alternating rotary dasherof a Washing-machine; and my invention consists in the parts Vand combinations of parts, as will be more fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view` in elevation disclosing my improvements. Fig. 2 is a view in transverse section of the same. Fig. 3 is a longitudinal section, and Figs. 4 and `5 are views of modifications.

1 represents awashing-machinehaving an ordinary cover 2, on which is secured the frame or bracket 3, carrying my improvements. This frame or bracket comprises a bed-plate 4, secured to cover 2, and end sections 5, having alined openings for the camshaft 6 and guide-rod 7. The cam-shaft 6 is mounted in the upper end of the frame or bracket 3 and supports the single endless cam 8. This cam is provided in the constructions shown in Figs. 1, 2, and 3 With a single continuous-cam flange 9, which latter rests and moves Within the slot 10 of stud 11. This stud is 'swiveled centrally in the upper face of the rack-bar 12, the latter being of such length as to give the dasher the requisite r0- tary movementin both directions. This rackbar 12 is slidingly mounted on the guide-rod 7, which latter is secured at its ends in the -,frame or bracket 3 and meshes with the pinion 13 on the upper end of the dasher or driven shaft 14. The cam 8 is provided with the internal or annular gear-Wheel 15, concentric With cam-shaft G, which gear-Wheel Serial No. 118,531. (No model.)

is'e'ngaged bythe pinion 16 on drive-shaft 17. It is evident, however, that instead of connecting up the cam by means of the internal gear 15 and pinion 16 the cam-shaft 6 may be extended beyond the machine and provided with a suitable hand-Wheel, as shown in Fig. 4, and it is also evident that instead of providing the cam 8 with a cam-ange 9 the cam may be provided with a groove and the stud 10 with a feather or spline fitting in said groove, as shown in Fig. 5.

With either construction shown it is evident that during one half ot' the revolution of the cam 8 the rack-bar 12 will be moved in one direction, thus rotating the dasher or driven shaft 14, and during the other half of the revolution the rack-bar will be moved in the reversedireetion, thus reversing the direction ofA rotation of the driven shaft or dasher.Y

The parts thus described are exceedingly simple, requirebut little finishing, and may be quickly and easily assembied and are particularly adapted for producing rotary movement in opposite directions of the dasher of a Washing-machine. `It is also evident that other changes in the construction and rela- Ativefarrangement of the several parts might be made without avoiding'my invention, and hence I would have it vunderstood that I do not restrict myself tothe particular construction and arrangement of parts shown and described; but,

Having fully described my invention, what vI claim as new, and desire to secure by Letters Patent, is-

1. The combination with a driven shaft, a pinion thereon and a rack-bar arranged to mesh with the pinion and provided with a swiveled stud, of a continuously-driven cam constructed to engage the swiveled stud on the rack-bar and reciprocate the latter, substantially as set forth.

2. The combination witha driven shaft, a

pinion thereon and a rack-bar arranged to mesh with the `pinion and provided with a swiveled stud, of an endless-cam flange constructed to it Within a groove in the swiveled stud, and means for rotating the cam, substantially as set forth. y

3. The combination with a driven shaft, a

pinion secured to the shaft, amok-bar mesh- In testimony whereof I have signed this ing with the pinion and a swiveled stud -atspecification in the presence of two subscrib- 1o taohed to the rack-bar, of a driving-shaft, a ing Witnesses. pinion secured thereto, an internal gear with Y 5 which said pinion meshes, said internal gear JOSEPH E HAUSFELD' being provided with an endless-cam ange Vitnesses: which engages the swiveled stud on the rack- CHARLES E.
